New #ISEPpapers! Hijacking and integration of algal #plastids and #mitochondria in a polar planktonic host: Ananya Kedige Rao et al. https://www.cell.com/current-biology/fulltext/S0960-9822(25)00392-6
"Hosts steal active plastids, mitochondria, and nuclei from the microalga #Phaeocystis... Stolen plastids increase in volume, and their photosynthetic activity is boosted... Stolen mitochondria transform into a network in close association with plastids"
We’re capturing the energy of #biologists100 by walking around with a polaroid frame, highlighting the incredible early-career researchers at the conference! ✨
We’re kicking things off with @JontyTownson, the #preLights conference reporter, who is uncovering the stories behind the #preprints being presented.
If you're at the meeting, please come say hi + get your snapshot! 📸
New research on #protists sheds light on #DeepSea energy sources https://www.whoi.edu/press-room/news-release/foraminifer/
Array of metabolic pathways in kleptoplastidic #foraminifera supports #chemoautotrophy in dark, euxinic seafloor sediments https://academic.oup.com/ismej/article/19/1/wrae248/7923457 by Fatma Gomaa et al.
"This species takes up unrelated organism’s #chloroplasts — #organelles that perform #photosynthesis... We know #kleptoplasty is happening here, but we needed to understand why this foraminifer is so successful in the dark, without oxygen"
Teaching about cells, organelles, cell transport or reproduction, etc.? I have resources to share.I’ve taught high school for many years, SPED to Honors. The differentiation & adaptations I made for SPED became sought after by other students, even at Honors level. I've worked hard at developing a helpful sequence of ideas, embedded vocabulary support, step-by-step graphics, and analogies.

A single cell's siesta: How non-moving #microbes manage to avoid bright light https://phys.org/news/2024-11-cell-siesta-celled-bright.html
Light-regulated #chloroplast morphodynamics in a single-celled dinoflagellate https://www.pnas.org/doi/10.1073/pnas.2411725121
"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."

Too much of a good thing is no good at all. Living organisms enjoy sunlight—in fact, they need it to stay alive—but they tend to avoid light that is too bright. Animals go to their shelter, humans have a siesta, even plants have mechanisms to avoid an overdose of light. But how do non-moving single-celled organisms deal with light that is too intense? Researchers at the University of Amsterdam have discovered the surprising answer.
Protein shell discovery reveals how #diatoms capture CO₂ so effectively https://phys.org/news/2024-10-protein-shell-discovery-reveals-diatoms.html
"diatom pyrenoids are encased in a lattice-like protein shell... not only gives the pyrenoid its shape, but it helps create a high CO2 concentration in this compartment. This enables Rubisco to efficiently fix CO2"
Tiny diatoms in the ocean are masters at capturing carbon dioxide (CO2) from the environment. They fix up to 20% of the Earth's CO2. A research team at the University of Basel, Switzerland, has now discovered a protein shell in these algae that is necessary for efficient CO2 fixation. This groundbreaking discovery can provide ideas for bioengineering approaches to reduce CO2 in the atmosphere.
